Specification of Letters Patent.

Patented Aug. 3l, i922.

To all whom t may concern Be it known that l, JAMES) l). Mosman, a citizen of the United States, and a resident ofthe city of St. Francois, in 'the county of St. Francois and State of Missouri, have. invented a new and useful lmprovement in Rotary Car Dumps, of vwhich the following is a specification.

My invention relates to means for dumping ore cars and thev like and has for its principal objects to expedite and cheapeu the operation ofdumping such cars. The invention consists partly in providing a resilient support for one side of a rotatable dumping frame and in providing means'i'or forcing said frame against said resilient support to initiate rotation of the frame. The invention also consists in locating the axis of rotation of said frame between said support and the center of gravity of the frame with a string'of loaded cars thereon. The inventionfurther consists in means for improving the purchase of the rhoisting means on saidframe. The invention further consists in the parts and combinations of parts hereinafterdescribed and claimed.

In the drawings which form part of this specification and wherein like reference characters indicate like parts wherever they occur.

Fig. l is anelevation of a dumping mech anism embodying my invention, a portion thereof being a section taken on the line ll of Fig. 2;

Fig. 2 is a side elevationthereof;

Fig. 3 is an end view, partly in section, showing the device after the frame has been rotated; and

Fig. l is a fragmentary side elevation showing the device after theframe has `been rotated.`

My device comprises a rotatable frame having rails 2 mounted thereon to form a trackway. The frame is arranged over a dumping pitand its trackway is arranged to be normally in alinement with and form a separate section of a main trackway on which rnn cars 30.

rEhe frame is provided at each end with a longitudinally projecting trunnion 3 so as to berotatable about a longitudinal aXis. The axis is located so as to be offset from the center of gravity of the dump with a string of loaded cars thereon. Preferably, the trunnions 3 are offset from the median plane of the frame, as indicated by dot'and dash lines in Fig. l. rllhe frame comprises suitable longitudinal inemberst and cross pieces 5. Supports Gare secured to the frame atv intervals and' support an angle iron 7 or like guard hanger above each rail ofv the track, saidy angle' irons 7 preferably being disposed with'a flangek S projecting horizontally over the track and located above the track a distance slightly greater than the diameter of afcar wheel 3l. Said guardhangers may be located so as to engage the tops of the cars or projections on the sides of the cars; or separate grappling membersA may be provided for each car. An upright 9cornprising an I-beam or the like is secured tothe frame near the middle thereof. A heavy coil s )ring l() is mounted on asupport ll adjacent to the lower endof said upright. A bracket l2 projects outwardly from the `lower end portion of Asaid upright Sand extends over said spring l0. A cnrve'd'channel iron 13 or the like is secured 'to said. upright' and said bracket. cable lit or chain is secured to the upright 9 near thetop thereof andone end of said cabley is connected by suitable rigging l5 to the end of the cable of any suitable winding mechanism 1G. By means vof said cable laF and upright said bracket is normally held against said spring, thus supporting the .frame in position-with its track.- way in alinement with the lmain trackway.

" The normal position ofthe device is shown `in F l, the frame being held rwith its trackway in alinement with the main trackway and the cable lll being' held taut. As above indicated, thereis a tendency for the frame to rotate because of the location of the longitudinal axis `with reference to the center of gravity. To dump the cars, the cable is pulled by means of the winding mechanism and the bracket l2 is 'thus forced against the spring l0. The pull is quicklyv released and mail the reaction of the spring initiates a rotation of the frame. Vlien the trame reaches the dumping position, the rotation is checked by means of the cable. The frame is rotated to normal position by means of the winding mechanism and cable. rfhe vbracket holds the cable away 'from the upright, when the required in vdumping and raising the frame by reason of the facts that the axis ot rotation is'o'ffset and the cable is held away from the upright.

An automatic stop may be arranged on the rails of the main trackway to prevent sol cars from running on to the frame while it is being dumped. lt is obvious that numerous changes may be made without departing from vmy invention and 1 do not wish to be limited to the precise construction shown.

What-I claim is:

.1. A car dump comprising a trackway, a frame pivotally mounted to rotate on an axis substantiallyv parallel with the trackway and having -a separate section of trackway mounted thereon, guard hangers on said :trame in position to overlap the wheels of a car thereon, and means vlfor normally holding said iframe with its trackway section in operative relation to the main trackway, said means comprising a resilient member in the path of one side of the frame adapted to aid in initiating the dumping movement thereof and in checking the movement to normal position.

2. A car dump comprising a trackway, a trame pivotally mounted to rotate on an axis substantially parallel. with t'he trackway and `having a separate section -o trackway mountedr thereon, guard hangers on said frame in position to overlap the wheels ot a car thereon, and means for normally holding said frame with its trackway section in operative relation to the` main trackway, said means comprising a resilient support for one side of said trame, and means for pulling said frame downwardly against said resilient support and 'for releasing` the pull to permit the resilient member to initiate a rotation of said frame.

3. A car dump comprising a trackway, a frame pivotally mounted to rotate on an axis substantially parallel with the trackway and having a separate section of trackway mounted thereon, said axis being offset from a vertical plane passing through the middle of said trackway, means on saidl frame for holding cars thereon, and means for normally holding said frame with its trackway section in operative relation to the main trackway, said means comprising a resilient member in the path of one side of the frame adapted to aid ininitiating the dumping movement thereof and in checking the movement to normal position.

4t. A car dump comprising a trackway, a frame pivotally mounted to rotate on an axis substantially parallel with the trackway and having a separate section of trackway mounted thereon, said axis being offset from a vertical plane passing. through the middle of said trackway, means on said -trame for holding cars thereon, and means for normally holding said frame with its trackway section in operative relation to the main trackway, said means comprising a resilient support Jfor one side of said frame, and means for pulling said frame downwardly against said resilient support to permit said resilient member to initiate a rotationof said frame.

5. A car dump comprising va frame pivotally mounted on a longitudinally extending axis, a trackway thereon adapted to accommodate the car wheels, guard hangers mounted on said -trame far enough above the `track to clear the car wheels slightly, an upright ixed at one side of said trame, a support for said side of the frame comprising a vertically acting` spring and means for pulling transversely of the trackway on the upper end of said upright, said longitudinal axis beingy located so as to be between said upright and the center of gravity of said carV dump with a string of loaded cars thereon and said pulling means being quickly releasable to enable the reaction of the spring to initiate the rotation of said trame.

6. A car dump comprising a frame pivotally mounted on a longitudinally extending axis, a trackway thereon adapted to accommodate the car wheels, guard hangers mounted on said 'frame far enough above the track to clear the carr wheels slightly, an upright 'tixed at one side of said frame, a support `iorsaid side ot the frame comprising a vertically acting spring `and quirkly releasable means 'for pulling transversely of the trackway on the upper end of said upright, said longitudinal' axis being located between said upright and the center of gravity of the car dump whereby the quick release of said pulling means enables the reaction oi' the spring to initiate the rotation of said frame.

7. A car dump comprising a frame pivotally mounted on a longitudinally extending axis, said axis being offset sidewise from the center of gravity of the car dump, a trackway on said fra-me adapted to accommod ate the lcar wheels, guard hangers mounted on said frame far enough above the track to clear the ear Wheels slightly, holding said cable away from said upright an upright Xed at the lighter side of said when the frame has been rotated, whereby frame, a support for said side of the frame leverage is obtained for raising said frame 10 comprising a vertically acting spring, a to normalposition.
